CASTING MACHINE.

Application filed January 4, 1922. Serial No. 527,016.

This invention relates to casting ma' chines and more particularly to centrifugah casting machines and spouts for-feeding centrifugal casting machines.

()ne of the objects of the present invention is to provide. a simple and practical spout for feeding horizontally disposed centrifugal casting machines. which spout will evenly distribute the molten metal to the interior of the Inold.

A further object is to provide a spout which may be easily and quickly moved into and out of operative relation withthe mold and protect the workmen from the splash of molten metal.

Other objects will be in part obvious and in part hereinafter pointed out in connection with the accompanying sheets of drawings illustrating a preferred embodin'ient of the present invention.

In these drawings wherein similar ref- (:rence characters denote corresponding parts,

Figure l is an elevational, sectional view of such parts of the apparatus as are necessary to understand the invention and.

Figure 2 is a, sectional plan view thereof.

Referring to the drawings indetail and more particularly. to Figure 1, 5 denotes a portion of the horizontally disposed rotating drum of a centrifugal casting machine. 'lhis drum is provided with an opening (3 through which is adapted to. pass a spout 7. This spout 7 has a laterally extending horizontal opening 8 and communicates with a funnel-like portion 10 mounted upon a base 11 which in turn is carried by a movable support 12. Between the parts 7 and 10 is interposed a thick curved splash guard 13 having a reversely curved part 14. In operation the movable support 12 is rolled up to the casting machine with the part 7 extending in through the opening 6 and the guardplate. 13 completely surrounding the end of the casting drum. The molten metal is then poured into the hopper or funnel 10 and flows inwardly and then laterally outward in a flat even sheet to the interior of the drum.

It will, of course, be understood that the drum is rotating at a high rate of speed while this is being done and were it not for the curved splash guard 13 the molten metal would probably flow out through the open end to the injury of adjacent workmen.

A further statement of the operation is thought to be unnecessary, as the construction and method of use Will be well understood from the above disclosure by those skilled in the art;

NVithout further analysis, the foregoing will so fully reveal the gist of this invention that others can by applying current knowledge readily adapt it for various applications without omitting certain features that, from the standpoint of the prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention, and, therefore, such adaptations should and are intended "to be comprehended within the meaning and range of equivalency of the following claims.

What I claim is:

1. A spout for use in centrifugal casting machines having a movable base, a hopper, a horizontal elongated portion connected with said hopper, said last mentioned )ortion having a horizontally disposed e ongated opening out through which the molten metal is adapted to pass.

2. A spout for use in centrifugal casting machines having a. movable base, a hopper, a horizontal elongated portion connected with said hopper, said last mentioned portion having a lu'n'izontally disposed'elongated opening out through which the molten metal is adapted to pass and a splash guard associated with said spout.

3. A spent for use in centrifugal casting machines having a movable base, a hopper, a horizontal elongated portion connected with said hopper, said last mentioned portion having a horizontally disposed elongated opening out through which the molten metal is adapted to pass and a splash guard interposed between the funnel and the horizontal part adapted to fit over theend of the casting drum.
